PRINTING BED FOR EMBOSSING OR IMPRINTING MACHINES.

Application filed March 17, 1926, Serial No. 95,371,;1111 in GreatBritain December 19, 1925.

This invention'relates to printing beds for embossing or imprintingmachines for embossing or imprinting selected designs, letters or othercharacters in or on suitable materials, for example, show oradvert1sementcards, price tickets, book covers and like articles of thekind in which the article, such as a card, ticket or the like, ofsufficient thickness for the purpose, in view of the manner in which itis to be operated upon, is overlaid with a sheet of thin paper, metal orother material, with, or without an adhesive coatii'ig, and hollow facedtype or embossing dies are laid upon this overlay and pressed thereon toindent the paper or the like, and the card, ticket or like article,around the contour of the design, letter or other character formed onthe type or die face, thereby severing from the paper or other overlaidmaterial, the part beneath the face of the type or die and causing thesevered portion to adhere to the card, ticket or other article.

The accompanying drawings show how the said invention can beconveniently and In these drawings Figure 1 is a plan view of a combinedform for holding the type or dies, and bed forthe support of this formand the card or the like which is to be embossed or imprinted by thetype.

Figure 6 is a side view and Figure 7 a plan illustratinga modlfiedconstruction of the improved form and bed.

Figure 8 is a side view and Figure 9 a plan illustrating a furthermodified construction hereinafter described.

Referring to Figures 1 to 5, 10 is a. bed for supporting the article tobe embossed or imprinted. This bed is provided with side plates 11which, together with bars 12 ex tending between them across the bed,serve as a form for holding the type or dies 13. Theseside plates aremounted to slide vertically with respect to the upper face of the bed,on pins 14 projecting laterally from the sides of the bed through slots15 in the said plates. The pins also pass through slots 16 in draw bars17 which are supported and guided between the sidesof the bed and theside plates. The slots-16 are inclined, as shown, so that they act ascam faces resting on the pins 14. i 1

By means of the draw bars and a handle 18, the bed can be moved to andfro along thelower ram plate 19 of a press. If desired, the draw bars 17may extend downwardly below the bottom of the bed 10 and by making thebed of equal width to the lower ram plate, these draw bars may serve aslateral guides for the bed, as shown in Figure 2. WVhen a pulling effortis exerted on the handle 18 the draw bars are moved from the position inwhich they are shown in Figure 3, the slots 16 sliding on the pins 14.'lhedraw bars are thus raised and lift the side plates 11 until thismovement is limited by the ends of the slots 15 coming into contact withthe pins 14. Thereafter the bed is drawn along by the said bars. When athrust is exerted on the handle 18 the draw bars are moved relatively tothe bed so as to allow the side plates to descend. When the form and bedare supported on the lower ram plate of a press, the handle 18 may beacted upon to draw the bed from below the upper ram plate of the pressthus simultaneously raising the bars 12 on which the type are carriedaway from the upper surface of the bed. On the other hand, by pushingthe handle 18, the draw bars, having first allowed the side plates todescend, serve to move the bed back to a position below the upper rainplate.

The upper face ofeach draw bar, at the part on which the correspondingside plate rests, can be inclined, the contacting face of the side platebeing similarly inclined so as to increase the distance through whichthe side plates are lifted for a given distance moved through by thedraw bars in the horizontal direction. I

WVhen the side plates are raised a sheet of suitable material, such as acard or ticket, can be withdrawn from or inserted between the faces ofthe type or dies'and the bed without disturbing the. dies or typesupported on the bars 12 in their raised position. I f

The said transverse bars, the edges of which may be straight, curved orof other convenient shape, in addition to providing a support for thetype, also act as space bar-s between the lines of type. The type ordies are provided with flanges which in use rest upon shoulders 12formed along the sides of the bars, the bodies of the type extendingdownwardly between and below the lower faces of the bars with freedom tomove vertically through a short distance relatively to the bars whenpressure is applied to their under faces by materials resting on the bedwhen the side plates are lowered, after which the type can be movedvertically downward, to make an impression in the said material bypressure exerted thereon, for example, by the upper ram plate of apress. The ends of the bars 12 are slidable in slots formedlongitudinally in the side plates, and means may be provided to holdthem clamped separately in the positions to which they are adjusted tohold the type between them. As clearly shown in Figure 5, the ends ofthese bars have slots formed therein in which an aligning bar 20 canrest. Thus when upward pressure is applied to the bars 12 (after thetype therein has been moved vertically upward) the bars will move upwardrelatively to the plate 11 and will also raise the aligning bar 20. Thisbar is slidable vertically on pins 21 and is pressed down by a leafspring 22. If desired the pins 21 can be replaced by clamping screws bywhich the bar 20 can be clamped on the said bars 12. A bed with type ordies set up between transverse bars clamped in this manner can becarried from place to place without disturbing the arrangement orsetting of the type or dies held therein.

In the case of type or dies movable vertically between the bars thethickness of the transverse bars atthe central or thicker part thereofis preferably less than the full height of the type or dies. Then, whenthe type or dies are resting on an article on the bed, the side platesand transverse bars being in the lower position, the backs of the typeor dies project above the top faces of the bars. If the bed is nowplaced in a press, the upper ram plate can be caused to exert pressureon the backs of the type or dies and press the faces of the type or diesinto the article to a depth limited by the thickness of the bars withwhich the ram plate comes into contact as soon as the backs of the typeor dies have been pushed down level with the tops of the bars.

In the modified arrangement illustrated in Figures 6 and 7, side plates23 with lower inclined edges 24.- are attached to the sides of a bed 25by screws 26 passing through slots 27 in the side plates which allow thelatter to be moved vertically relatively to the bed. The bed is providedwith a draw bar 28 by means of which the bed plate can be moved to andfro across the lower ram plate 30 of a press. At convenient partsof theramplate, along the sides thereof, projections 30 are provided havinginclined upper faces so that when the lower edges of the side plates aredrawn over these projections the side plates are thereby raised. Theside plates 23, as in Figure 1, are provided with longitudinal groovesholding type supporting bars 12.

A further modification is illustrated in Figures 8 and 9. Side plates3]. are attached laterally to the bed by screws 32 passed throughinclined slots 33 in the plates. A spring 34 attached to the bed by ascrew and having its free ends respectively resting on the side plates,moves the latter so as; to bring the ends of the slots 32 into contactwith the screws A draw bar 28 is attached to the bed whereby it can bemoved to and fro along a ram plate or other suitable surface having lugs37 projecting laterally therefrom to serve as stops for the side plates3 \Vhen the side plates have been brought into contact with the lugs thebed can be drawn between the side plates so that the screws 35 are movedalong the slots 33 raising the side plates. When the bed is pushed backthe spring 34 moves the side plates longitudinally, so that the slotstravelling across the screws cause the side plates to move downwardly.

The arrangement hereinabove described forms a combined bed and form inwhich the type or dies when set are held in such a manner that a numberof cards, tickets or other articles can be embossed or imprinted withoutreadjustn'ient or resetting of the type or dies. The bed and form withthe type or dies set therein constitutes an independent unit which canbe moved from place to place and used in any press of suitableconstruction. The raising or lowering of the type or die carrying formfrom or towards the bed is effected automatically by the pull or thrust011 the draw bars. Moreover, the transverse bars are so arranged thatthey constitute a stop limiting the pressure to which the-type or diefaces can be subjected, so that the type or dies are protected againstbeing damaged by excessive pressure and are prevented from penetratingtoo deeply into the card, ticket or like article which is to be embossedor imprinted thereby.

hen the handle 18 is drawn away from the side plates 11, the said sideplates and type supporting bars mounted therein are raised away from thebed 10 a distance which is limited by the pins 1 1. This allows a cardor like article to be embossed to be placed upon the bed 10, thethrusting of the handle towards the side plates then causing thesubsequent lowering of the said side plate and type supporting bars tobring the face of type carried by the bars into contact with the articleto be embossed. To prevent the exertion of pressure by the type upon thearticle on the bed 10 during the movement of the handle towards the sidewalls, the type is arranged to be vertically movable relative to thetype supporting bars which are likewise vertically movable relative tothe side walls. When the type is moved into contact with the article tobe embossed, the printing bed is moved between the upper and lower ramplates of a press by which pressure is exerted to force the cuttingedges of the type into the article to be embossed. Subsequent to theembossing, the side walls and type supporting bars can be raised ashereinabove described to permit 4 the removal of the embossed article.
